Rotating shaft 3 penetrates the right side wall of deep well 1, the claw of three-jaw mechanical arm 4 is designed as streamline, for adapting the streamline appearance of fin 6, can be closely combined with the outside of fin 6;Meanwhile, the design of this multi-claw structure provides the thrust from top to bottom for fin 6, forms the clamping of stable for fin 6, is favorable to the surface of fin 6 even force, avoid large-scale deviation and the situation of shaking occurs. Three-jaw mechanical arm 4 controls the lateral displacement of fin 6, fin 6 is connected below hanging plate 9 by suspension assembly 8, suspension assembly 8 includes pulley mechanism and suspension rope 82. Pulley mechanism includes fixed pulley 84 and movable pulley 81, fixed pulley 84 is fixedly connected with hanging plate 9;Movable pulley 81 is fixedly connected with fin 6 by bolt, the height of movable pulley 81 does not exceed the upper surface of fin 6. Suspension rope 82 is as safety redundancy structure, suspension rope 82 upper end is connected in the lower surface of hanging plate 9, suspension rope 82 lower end is connected with the lifting ring 83 of the upper surface of fin 6.

[0033] The contact surface of fin 6 and three-jaw mechanical arm 4 is provided with not less than a group of sensor units 5, sensor units 5 include pressure sensor, displacement sensor and contact sensor. Deep well 1 left side wall is provided with spring bed buffer pad 7, the internal structure of spring bed buffer pad 7 as shown in Figure 5 Fig. 2, because fin 6 is heavy, if there is no buffer, when the wall of deep well 1 and fin 6 contact, the surface of both will be subjected to great impact force, the spring compression in spring bed buffer pad 7 can increase the braking stroke, play the role of buffer.

[0034] The working process of the lock device for the lifting fin is as follows:

[0035] S1, the fin 6 receives a locking instruction, the pulley mechanism slowly lifts or lowers the fin 6, adjusts the fin 6 to a preset height, and the displacement sensor records the fin 6 movement information in real time and monitors the displacement change.

[0036] S2, the power motor 2 works, power is transmitted to the three-jaw mechanical arm 4 through the rotating shaft 3, and the three-jaw mechanical arm 4 is gradually extended and retracted; at the same time, the pressure sensor records the pressure information of the gripper of the three-jaw mechanical arm 4, and under the premise of ensuring that the gripper of the three-jaw mechanical arm 4 does not slide with the fin 6, the pressure on the fin 6 is reduced to avoid damage to the surface of the fin 6.

[0037] S3, the gripper of the three-jaw mechanical arm 4 contacts the surface of the fin 6, and the unique design of the gripper that matches the shape structure of the streamlined surface of the fin 6 is beneficial to tightly hold the fin 6 and form a stable contact and clamping state;

[0038] S4, the power motor 2 works in a low-speed and high-torque mode, slowly and stably pushes the fin 6 to the spring bed buffer pad 7, and in the pushing process, the displacement sensor records the displacement information of the fin 6 in real time, which is used to calculate the distance between the fin 6 and the spring bed buffer pad 7. According to these real-time distance data, the pushing speed and strength of the three-jaw mechanical arm 4 are dynamically adjusted to ensure that the fin 6 always maintains a safe and stable running state during the approach to the spring bed buffer pad 7, avoiding unnecessary damage to the fin 6 due to excessive pushing speed or improper strength.

[0039] S5, the fin 6 contacts the spring bed buffer pad 7, the contact sensor captures the contact signal between the fin 6 and the spring bed buffer pad 7, the power motor 2 stops power output, and the fin 6 is locked. When the fin 6 contacts the spring bed buffer pad 7, the spring inside the spring bed buffer pad 7 elastically deforms, effectively absorbing and dispersing the impact force received by the fin 6 during the contact process. This buffering effect can reduce the potential damage caused by impact to the fin 6, ensuring the structural integrity and functional stability of the fin 6 during the entire locking process. Whether in a high-intensity cruising state or in a complex and variable working environment, this buffering mechanism can provide reliable and safe locking protection for the fin 6.

[0040] Therefore, the application adopts the above-mentioned locking device and method for lifting the fin, the claw of the three-claw mechanical arm is designed as a streamline, which is used for adapting the streamline appearance of the fin and avoiding the stress concentration of the fin, the pressure sensor, the displacement sensor and the contact sensor are combined to enable the three-claw mechanical arm to accurately clamp the fin, and the damage to the fin is reduced while clamping the fin; the spring bed cushion is used to reduce the damage caused by the fin impacting the deep well and the damage to the fin caused by the ship body swinging.
